I bought an R4 card a year or so ago. Just regular R4 card, and it's unsupported now (last Firmware version listed on the site is 1.18 from April '08). And so I have a question. What's the fundamental difference between my current card and a R4 SDHC card. I know that the firmware for the R4 SDHC doesn't work on my card. But I want to know if it's worth getting a new card, or if my old one will still be able to use the patches for new roms that come out.
